Jerusalem -- in Hebrew it is Jerushalaim = which stands for Jerusha( יְרוּשָׁה ) la’em ( להם ) which means : to them.
Thus it means "their (=the Jews) HERITAGE”. Jerusha means heritage,inheritance, la’em means to them, thus their (the Jews) heritage. That's what my Hebrew teacher, Chief Rabbi Medalie taught us in the Hebrew classes in 1969-1970. That's how it was explained to me when I was living and working as a Registered Nurse in Jerusalem.
Peace in Hebrew is "shalom" (in Arabic it is "sala'am" which has nothing to do with the "salem" of the English word Jeru"salem"
Rivka ( my Hebrew name) Shalom Lachem (שלום לכולכם)
Jerusalem is Jewish by HASHEM's decrete !!!!
